A middle schооl wаnted tо evаluаte the efficacy of a 6-month after-school program designed to teach 7th grade students math concepts. The program involved weekly sessions that used computer apps that had tutorials and practice problems. Students (n= 100) who were struggling in math (based on 6th grade math scores) were included in the program.  At the beginning of the year the students took a math pretest (reliability = .45) and scored a mean of 15 (out of 100). After 6-months 65 of the 100 students remained in the program.  These 65 students were posttested and scored an average of 45 on the identical test that was used at pretest (out of 100).  The reliability of the posttest was .75. For each threat to internal validity, define the threat and briefly discuss if this threat is likely. History
